Foil 23 More on Sharing in Tango

From Pictorial View of Tango Features with tutorial SIGGRAPH 98 Orlando -- July 19-23 98. by Geoffrey C. Fox
1 Tango can share any client or server application whose state can be determined and set. Tango finds the state from the master and transmits it to the slave clients
  • For efficiency, Tango usually transmits "the change in state" and not state itself -- for spring it is as easy to transmit absolute state x as change dx in state. For chat, change in state (latest text typed) is natural.
  • For server applications, one finds and sets state through web interface which can be URL (perhaps with CGI extension) or even CORBA interface to a distributed object.
2 Porting an application to Tango, requires sending messages from master with state (change) and receiving them on slave. Hardest perhaps is knowing what the state is!
